A fluid infusion system as described herein includes a number of local “body network” devices, such as an infusion pump, a handheld monitor or controller, a physiological sensor, and a bedside or hospital monitor. The body network devices can be configured to support communication of status data, physiological information, alerts, control signals, and other information between one another. In addition, the body network devices can be configured to support networked communication of status data, physiological information, alerts, control signals, and other information between the body network devices and “external” devices, systems, or communication networks. Such external communication allows the infusion system to be extended beyond the traditional short-range user environment. One particular system embodiment includes a network router device that functions as a centralized storage, processing, and routing unit for data received from the body network devices. The network router device is configured to generate HTML documents (web pages) to facilitate Internet-based setup, management, and control.

A method and system for security monitoring in a computer network has a packet sink with filtering and data analysis capabilities. The packet sink is a default destination for data packets having an address unrecognized by the network routers. At the packet sink, the packets are filtered and statistical summaries about the data traffic are created. The packet sink then forwards the data to a monitor, the information content depending on the level of traffic in the network.

High availability BGP4 is based on redundant hardware as well as redundant software that replicates the RUN state of BGP4. There are two copies, respectively active and backup, of BGP4 running on two separate redundant hardware platforms. All BGP4 internal implementations apply various methods to replicate the running state of BGP4 independently of peer network routers. When this hardware or software fails on one redundant hardware platform, peer routers are unaware of the failure. Internally, based on duplicative states, the local router recovers from the failure and keeps the protocol running. During the recovery period, the local router can bring up a backup again. In the HA architecture, these activities are not detected by peer routers, such that there is no instability to the Internet backbone caused by BGP4 failure.

Methods, apparatuses and systems directed to a network traffic synchronization mechanism facilitating the deployment of network devices in redundant network topologies. In certain embodiments, when a first network device directly receives network traffic, it copies the network traffic and transmits it to at least one partner network device. The partner network device processes the copied network traffic, just as if it had received it directly, but, in one embodiment, discards the traffic before forwarding it on to its destination. In one embodiment, the partner network devices are operative to exchange directly received network traffic. As a result, the present invention provides enhanced reliability and seamless failover. Each unit, for example, is ready at any time to take over for the other unit should a failure occur. As discussed below, the network traffic synchronization mechanism can be applied to a variety of network devices, such as firewalls, gateways, network routers, and bandwidth management devices.

A method and apparatus for packet coalescing within interconnection network routers. In one embodiment, the method includes the scan of at least one input buffer to identify at least two network packets that include coherence protocol messages and are directed to the same destination, but from different sources. In one embodiment, coherence protocol messages within the network packets are combined into a coalesced network packet. Once combined, the coalesced network packet is transmitted to the same or matching destination. In one embodiment, combining multiple network packets (each containing a single logical coherence message) into a larger, coalesced network packet amortizes the fixed overhead of sending a network packet including a single coherence message, as compared to the larger, coalesced network packet, to improve bandwidth usage. Other embodiments are described and claimed.

In a network router, a tree structure or a sorting network is used to compare scheduling values and select a packet to be forwarded from an appropriate queue. In the tree structure, each leaf represents the scheduling value of a queue and internal nodes of the structure represent winners in comparisons of scheduling values of sibling nodes of the tree structure. CBR scheduling values may first be compared to select a queue and, if transmission from a CBR queue is not timely, a packet may be selected using WFQ scheduling values. The scheduling values are updated to reflect variable packet lengths and byte stuffing in the prior packet. Scheduling may be performed in multiple stages.

A delay measurement technique according to an embodiment according to the present invention is based on the precept, ascertained by the inventors, that a link between network nodes will often contribute to the delay encountered between several different pairs of network nodes. Such a technique identifies the path between each pair of nodes by a list of links that form the path. Paths that are orthogonal are treated as being necessary for describing the delays encountered between nodes, and, once the requisite set of orthogonal paths has been derived, all other paths can be described in terms of one or more of these orthogonal paths. Such a technique also lends itself to matrix representation of the paths, and the use of matrix manipulation techniques in deriving delay and jitter.

Disclosed is a content based router, system and method of operation. Upon receipt of a data packet at in ingress router, the ingress router matches the content of the data packet against stored user subscriptions. In one embodiment, the content is described using XML data and the user subscriptions are defined by XML queries. The router assigns a routing label to the data packet based on the matching, and transmits the data packet to a second network router. Intermediate routers along the packets path then use the assigned label in combination with stored routing tables in order to determine next hop routing. Upon receipt at an egress router, the content of the message is matched against user subscriptions for those users serviced by the egress router, and the egress router provides the data packet to those end users whose subscriptions match the content. The assigned routing labels may define routing paths or routing trees.
